Endless chitin 105 1j7 17 are presefltifpr siib stantizilly r'fi l,tr i ljthrcu'g h m er li Pivotally cb'nneted w 'iemd'siisp'eiided be tween the chain belts 1717 are a multiplicity of soap holders or supports constructed so as to normally hang in a horizontal position during their passage throughthe above mentioned compartment. Each soap-holder comprises a substantially U- shaped hanger preferably formed in one piece and embracing an apertured' crosspiece 18 and'a pair of uprights 19, slightly bent outwardly at their upper ends and each terminating in a lug 20 apertured to receive a pivot pin for suspending the hanger with respect to the chain belts. Each upright is enlarged or reinforced at its bottom for a purpose to presently appear. Disposed upon and at right angles to each cross-piece 18 is a one-piece saddle embracing a fiat plate 21 having an upwardly extended lip 22 at its rear end having a pair of soap engaging points. 21 at its front end and having a central, depending, apertured lug 23. This apertured lug is detachably secured to the cross-piece ofa hanger as by a bolt 24:. The plate 21 is centrally cut away as at 5 in order that little soap resisting surface be present and at the same time to lighten construction. The endless chain belts equipped with complemental soap-holders as above described will hcreiuafter be termed the endless conveyor.

FeecZ.Soap is first molded as usual, then slabbed and immediately introduced to a cutting machine (not shown in the drawings) and cut into bars, blocks or cakes 26. From the cutting machine, the bar-soap is fed directly to compartment 11 by means of an apron 27. The soap as fed is of solidified plastic form, the surface of which is in a semi-crystalline, non-uniform condition. Furthermore, the soap is in a 'a-porous or moist condition interiorly and exteriorly considered and it is essential that this moist condition be preserved indefinitely so that said soap retains its specific properties and original weight. To that end, I treat soap to rapidly develop a superficial, uniform and translucent film or skin visibly free of crystalline salts and of an infinitesimal penetration. Thus, while the soap surface is modified, the composition of the soap is not altered. The bars of soap are fed to com partment 11, in a positive manner in abut ting positions by the apron 27. In practice, a single bar of soap is fed forwardly upon oppositely disposed sets of horizontal guides or finger pieces 28 fixed in the same plane with said apron top surface. The finger pieces form continuations of vertical guides 29 and are of proper size to hold or support but a single cake. As the endless conveyer moves upward between said opposed sets of finger pieces 28, a bar of soap is bodily lifted from 011' said fingers by the saddle of a hanger and another bar of soap is moved upon said ifin'gerpieces by the apron 27. It

sometimes happens that the cutting machine fails to entirely sever adjacent bars of soap so that when the saddle lifts its proper bar of soap a second bar is attached thereto. Should this condition continue, jamming of the apparatus parts with likelihood of breakage thereof is present. To guard against this, I-have provided immediately above the apron 27 a pivotal, horizontally disposed trip-plate 30 which carries a spring-pressed, vertical member having at its free end a roller 31. Normally this roller engages the underside of a lip 32, which is fixed to the housing or casing 10 and this maintains plate 30 in position for tripping. When two engaging bars of soap move upward, the outermost bar abuts against the underside of plate 30 with the result that the plate is moved around its pivot point so that the.

roller 31 rides outward or away from retaining lip 32. This movement of plate 30 is sufiicient notice to the operator in charge to immediately stop the operation of the apparatus. It may be here stated that the tension of the spring of the vertical member carrymg the roller 31 is such that should adjacent bars of soap but slightly adhere,

the same may be caused to separate by said plate 30 without tripping thereof. In such case the bar of soap adhering to the up wardly moving bar is retained against upward in ovement.

embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and while I have in the present instance shown and described the preferred embodimentl thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages and that I have in mind the treatingof plastic articles other than soap.'

That I claim is 1. In apparatus of the character stated,

feed mechanism embracing in combination an endless conveyer provided with a plurality of free swinging holders, means operative in the path of travel of said holders for supporting a solidified plastic article, means for continuously feeding solidified plastic articles in abutting relation toward said supporting means, means for guiding a holder to such a supported article and a safety element perative to be tripped by abutting yet unsevered pairs of said articles as moved by a single holder, said element being disposed in immediate juxtaposition to said supporting means.

2. In apparatus'of the character stated, feed mechanism embracing in combination an endless conveyer provided with holders, each holder being designed to carry a solidified plastic article of predetermined size, means for feeding such articles to said conveyer, and means operatively positioned in immediate juxtaposition to the place of feeding said articles operative to be tripped by an article of a size of predetermined excessiveness as moved by a' holder.

3. In apparatus of the character stated, feed mechanism embracing in combination an endless conveyer provided with holders, each holder being designed to carry a solidified plastic article of predetermined size, means for feeding such articles to said conveyer, a fixed element above the feeding means and a movable element having cushioned roller relation with the underside of the fixed element, said movable element being designed to be shifted away from the fixed element by an article of a size of predetermined excessiveness as moved by a holder.

4:. In apparatus of the character stated, feed mechanism embracing in combination an endless conveyer provided with a plurality of free swinging holders, oppositely disposed, spaced vertical guide pieces upon opposite sides of said holders for preventing swinging of the holders adjacent the apparatus feed, each guide piece terminating in a horizontal portion to form a fixed support, the inner ends of which are provided with vertical stops and means for feeding solidified plastic articles continuously in unrestricted, abutting relation toward said support whereby an individual article is always positioned upon the support irrespective of the location of an advancing holder.

5. In apparatus of the character stated, feed mechanism embracing in combination an endless conveyer provided with a plurality of free swinging holders, oppositely disposed, spaced, vertical guide pieces upon opposite sides of said holders for preventing swinging of the holders adjacent the apparatus feed, the outer guide pieces being extended outwardly in a horizontal manner and the inner guide pieces being extended inwardly in a horizontal manner and then vertically the combined parts forming a support and a stop and means for feeding solidified plastic articles continuously in unrestricted, abutting relation toward said support, whereby an individual article is always positioned upon the support irrespective of the location of an advancing holder.

6. In apparatus of the character stated, feed mechanism embracing in combination an endless conveyer provided with a plurality of holders, a fixed support constructed for the travel therethrough of the holders, means for feeding solidified plastic articles of predetermined size continuously in unrestricted, abutting relation toward said support for removal by the holders in sequential relation and a safety element operative to be tripped by an article exceeding said predetermined size as moved by a holder.

7. In apparatus of the character stated, feed mechanism embracing in combination an endless conveyer provided With, a plurality of holders, a fixed support constructed for the travel therethrough of the holders, means for feeding severed solidified plastic articles continuously in unrestricted, abutting relation toward said support for removal by the holders in sequential relation and a safety element operative to be tripped by an unsevered pair of said articles as moved by a holder.

8. In apparatus of the character stated, feed mechanism embracing in combination an endless conveyer adapted for substantially vertical travel provided with a plurality of free swinging holders each designed to carry an article of predetermined size and a safety element operative to be tripped by an article exceeding said predetermined size as moved by a holder.
